Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to increase the uniformity of the seeding material embedment depth by the front and rear openers (C) and to eliminate unbalanced lateral loads on the crop. The mill contains a bunker 2 for sown materials with seeding, devices 3 and 4, sem wires 5 and two single-row C 7 mounted on leashes 8 with support rollers 9, as well as rolls, and rollers 13. Supporting the rollers of the first and second rows are installed one after another. The openers 7 of the first row are located on the left side, and the openers of the second row are located on the right side of their track rollers 9. The sowing machines 3 and 4 send seed and fertilizer to the grooves formed by the C 7 drives through this wire 5 The support rollers 9 of the second row are followed by the tracks of the track rollers of the first row C ensure uniform seeding of seed and fertilizer by all C. on the cross Ayush, s by exposing the soil with a strong resistance. 2 Il. 1C cl

The invention relates to agricultural machinery, in particular to universal crops for sowing grain, leguminous crops, large crops, grasses, feeding and applying a full dose of mineral fertilizers.

The purpose of the invention is to improve the uniformity of the seeding material embedment depth by the front and rear openers and to eliminate unbalanced lateral loads on the sow.

FIG. 1 shows a universal plant, side view; in fig. 2 is a diagram of the arrangement of the coulters and packers of rollers, top view.

The universal crop contains frame 1 and bunker 2, CONSTANTING in two parts for seeds and mineral fertilizers.

In the lower part of the bunker, there is a bobbin 3 and a bobbin-pin 4 sowing apparatus for sowing seeds and fertilizers, respectively, which are connected with sem guides 6, installed behind the single-disc coulters 7, through the seed pipes 5. in the front and rear row.

Single disc coulters are mounted on drivers 8, and support rollers 9 are installed on the side of the coulters on the driver, which are connected to the driver 8 by means of a device 10 for adjusting their height position relative to the disks of the coulters. Following the openers 7 on spring leads 11, axles 12 are fixed with press rollers 13 mounted on them.

The track rollers 9 of the second row of openers are installed behind the track rollers of the first row.

The single disc coulters 7 of the first row are located on the left side of their track rollers, and the coulters of the second row yes are located on the right side of their track rollers 8.

Selka works as follows.

Seeds and fertilizers from the hopper 2 are sown with sowing devices 3 and 4, from where they are fed with seed pipes 5, as well as this guide 6, into the grooves opened by the coulter disc 7.

Seeds sown by the front and rear openers are closed in and rolled up by rollers 13. Adjusting device 10 is provided for sowing various materials, which change the depth of the coulter disk 7 by changing the position of the support roller 9 relative to the opener within 1 -10 cm with interval I see. The arrangement of the support rollers 9 of the first and second row of openers moving along the ground one after the other along one track increases the uniformity of a predetermined embedment depth of the sown material in the soil. Location of the openers 7 of the first

from the row on the left side, and the coulter disks 7 of the second row on the right side of their support rollers 9 (Fig. 2) allows to balance the forces PI and p2 of soil resistance on the coulters, thereby eliminating the unbalanced lateral loads on

0 will improve the straightness of the stroke of the shovel, prevent it from contracting to one of the sides, ensure observance of the constant butt spacing, and increase the uniformity of the depth of the coulters across the entire width of the shoal.
